invert_selection

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations and only a single verb, the description fails to disclose behavioral traits such as whether the operation is destructive, reverts on next action, or affects stored selections. The minimal text leaves the agent to infer behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no extraneous words. It is appropriately concise for a simple toggle operation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is minimal but largely sufficient for a straightforward tool with no parameters. However, it lacks detail on the exact outcome (e.g., what 'invert' means for fixture selection) and does not leverage the existence of an output schema to describe return values.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters and schema coverage is 100%, so the description needs no additional parameter explanation. The baseline score of 4 is appropriate as no parameter-related value is missing.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'invert' and the resource 'current fixture selection', making the tool's purpose unambiguous. However, it could further clarify that 'invert' means selecting all unselected fixtures and deselecting currently selected ones.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No information is provided about when to use this tool versus alternatives like 'next_fixture' or 'fix_selection'. The description gives no context for appropriate usage or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
